Longest Common Subsequence 给出两个字符串,找到最长公共子序列(LCS),返回LCS的长度。 说明 最长公共子序列的定义: • 最长公共子序列问题是在一组序列(通常2个)中找到最长公共子序列(注意:不同于子串,LCS不需要是连续的子串)。该问题是典型的计算机科学问题,是文件差异比较程序的基础,在生物信息学中也有所应用。
@ 1.问题描述 给定两个字符串 text1 和 text2,返回这两个字符串的最长 公共子序列 的长度。如果不存在 公共子序列 ,返回 0 。 一个字符串的 子序列 是指这样一个新的字符串:它是由原字符串在不改变字符的相对顺序的情况下删除某些字符(也可以不删除任 何字符)后组成的
For example,"ace"is a subsequence of"abcde". Acommon subsequenceof two strings is a subsequence that is common to both strings. Example 1: Input:text1 = "abcde", text2 = "ace"Output:3Explanation:The longest common subsequence is "ace" and its length is 3. Example 2: Input:text1 = ...

https://leetcode.com/problems/longest-consecutive-sequence/ 该题目要求从一个数组中找出可以组成的最长连续序列,即该序列的所有元素每次递增1,要求输出这个序列的长度。 首先将这个数组由大到小排序。之后通过遍历数组,比较当前元素和上一个的大小来判断是否为连续序列。判断的结果有三种:1、相差为1,则表明连续,...
